In 2012 the price of soy grew over 30%, and this summer wheat and corn hit respectively +30% and +38%.

At the same time, banks and financial investors are making a killing. World Development Forum estimates that Barclays makes up to £340 million a year from betting, or speculating, on food prices. In the last five years, the amount of financial speculation on food has nearly doubled, from $65 billion to $126 billion (read more information here).
